SPECIFICATION forming part of Letters Patent No. 273,091, dated February27, 188

Application filed November 8, 1882. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. IRISH, a citizen of the United States,and a resident of Grand Isle, in the county of Grand Isle and StateofVermont, have invented a new and valuable Improvement inFruit-Evaporators and I do hereby declare that the following is a full,clear, and exact description of the con struction and operation of thesame, reference being had to the annexed drawing, making a part of thisspecification, and to the letters and figures of reference markedthereon.

The figure of the drawing is a vertical sectional view of my device.

This invention has relation to apparatus for evaporating the moisturefrom fruit; and it consists in the construction and novel arrangement ofa close, hollow base-pan, having above it a series of close, hollowshelves, supported by intermediate upright central tubes, formingpassages communicating with the chambers of the shelves and in line withan upper feeding vessel or drum, forming an entire hollowshelved vessel,and in connection therewith an open-bottom covering or jacket designedto envelop the entire vessel.

The invention also consists, in combination with the shelved hollowvessel and its jacket, of movable perforated under shelves, suspendedfrom the hollow main shelves, in position close to the bottoms thereof,all as hereinafter set forth, and particularly pointed out in theappended claims.

In the accompanying drawing, the letter A designates a hollow-shelvedvessel, which is constructed entire, and consists of a close basepan, a,made deep enough to hold a sufficient quantity of water for the purposehereinafter described, close hollow shelves 1), of less depth than thebase-pan, short central supportingtubes, 0, and the upper feeding vesselor funnel, d. The hollow shelves have each a top, 0, bottom g, and sidewall h, and are arranged one above another in series, beingsupported inposition by the intermediate short tubes, 0, which form passages is,communicating with the hollow chambers lof the shelves, the lower tubecommunicating with the hollow interior of the base-pan, from the centerof the top of which it extends upward, supporting the lower shelf of theseries. The tubes 0 are in line with each other vertically, and are alsoin line with the upper drum or feeding-funnel d, with the interior ofwhich the upper tube is in communication. This feeding drum or funnel isprovided with a cover, in, which is also provided with a small funnel,n, for convenience in pouring small quantities of water down into theinterior of the shelved vessel. The outer edges of the hollow shelvesare usually connected to each other and to the upper drum, d, by meansof bracing-strips s, which serve to strengthen the structure and aid inkeeping the shelves in proper horizontal position when loaded.

B represents the enveloping-jacket, which is in general form similar tothe vessel A, but large enough to cover it completely. Its bottom isopen and its upper portion is conical or tapering, and is made with anopening, 2, at top for the escape of the moisture from the fruit on theshelves. I

0 indicates the under shelves, which are made in pan shape, having sidewalls 1; and perforated bottoms z. tral openings, 1', and are placed onthe tubes 0 before the latter are connected to the hollow shelves. Theunder shelves are movable on the tubes, and are held up in closerelation to the bottoms of the hollow shelves by movable catches 1..When fruit is to be placed on one of these under shelves, the catchesare unfastened and the under shelf lowered upon the shelf below. Thefruit is then placed upon the perforated bottom and the under shelf israised up in close relation to the hollow shelf above it, to which it isconnected by means of the catches.

The jacket or cover having been placed over the evaporating-vessel A,heat is applied by means of hot water or steam. 1f hot water is used,the vessel should be filled therewith. If steam is employed, sufiicientwater should beintroduceid into the base-pan to generate the steam, whenthe vessel and its cover are placed upon a suitable furnace or heater.

This evaporator is of simple construction, and can be used with thegreatest facility.

When the jacket is removed, access is bad to the shelves from all sides.Asinglecentral passage serves for the introduction of water and for theescape of steam. By means of These shelves have cen- 7 5 the undershelves the bottoms of the heated hollow shelves are utilized, so thateach shell" has a double capacity.

Having described this invention, What I claim, and desire to secure byLetters Patent, 1s-

1. The close, hollow base-pan a, having above it a series of close,hollow shelves, 1), supported by intermediate upright central tubes, 0,forming passages 70, communicating with the chambers l of the shelves,and in line with an upper feeding vessel or drum, d, the whole formingan entire hollow-shelved vessel, substantially as specified.

2. The combination, with the hollow-shelved vessel A, having thebase-pan and central tubes supporting the shelves, of the open-bottomenveloping-jacket B, having an opening at its top, substantially asspecified.

The combination, withthehollow-shelved vessel A and itsem'eloping-jaeket B, of the movable perforated under shelves, 0,suspended by catches from the hollow main shelves, in position close tothe bottoms thereof, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

CHARLES B. IRISH.
